NEW QUESTION # 150
If you decide you want to see all of the marks in the view at the most detailed level of granularity, you can
__________________ the view.

A. split the measures
B. sort the measures
C. disaggregate the measures
D. aggregate the measures
E. break-down the measures

Answer: C

Explanation:

The different aggregations available for a measure determine how the individual values are collected: they can be added (SUM), averaged (AVG), or set to the maximum (MAX) or minimum (MIN) value from the individual row values.
For a complete list of the available aggregations, check out - List of Predefined Aggregations in Tableau.
The level of detail is determined by the dimensions in your view-for information about the concept of level of detail, see How dimensions affect the level of detail in the view.
Disaggregating your data can be useful for analyzing measures that you may want to use both independently and dependently in the view. For example, you may be analyzing the results from a product satisfaction survey with the Age of participants along one axis. You can aggregate the Age field to determine the average age of participants or disaggregate the data to determine at what age participants were most satisfied with the product.
Disaggregating data can be useful when you are viewing data as a scatter plot. See Example: Scatter Plots, Aggregation, and Granularity.

NEW QUESTION # 151
Which of the following are correct ways to define a join in Tableau version 2020.3 and above?

A. Right-click a physical table and click on open to go to the Join/Union canvas in the logical layer and add joins or unions.
B. Double-click a physical table to go to the Join/Union canvas in the logical layer and add joins or unions.
C. Double-click a logical table to go to the Join/Union canvas in the physical layer and add joins or unions.
D. Right-click a logical table and click on open to go to the Join/Union canvas in the physical layer and add joins or unions.

Answer: C,D

Explanation:
Remember that joins are defined in the physical layer and relationships in the logical layer.
You can still specify joins between tables in the physical layer of a data source. Double-click a logical table to go to the Join/Union canvas in the physical layer and add joins or unions.
Every top-level, logical table contains at least one physical table. Open a logical table to view, edit, or create joins between its physical tables. Right-click a logical table, and then click Open. Or, just double-click the table to open it.

When you create a data source, it has two layers. The top-level layer is the logical layer of the data source. You combine data between tables in the logical layer using relationships.
The next layer is the physical layer of the data source. You combine data between tables at the physical layer using joins. For more information, see Logical and physical tables in the data model

Explanation:
You can use a story to present a data narrative to lead your audience to your conclusions, or to assemble a sequenced analysis to share with collaborators. A story is a sequence of visualizations that work together to convey information. You can create stories to tell a data story, provide context, demonstrate how decisions relate to outcomes, or to simply make a compelling case4

NEW QUESTION # 155
How can you change the Default Aggregation for a measure in Tableau?

A. By right clicking the dimension -> Default properties and choosing Aggregation
B. By right clicking the measure -> Default properties and choosing Aggregation
C. By double clicking on the measure, and then choosing Window -> Default Aggregation
D. By changing its properties manually every time we need to use it

Answer: B

Explanation:
According to the official Tableau documentation:

Dimensions don't have aggregation properties, and adding properties manually each time defeats the whole DEFAULT aggregation purpose. Window tab doesn't have any default aggregation option!

NEW QUESTION # 156
True or False: To concatenate fields, they must be of same data type

A. False
B. True

Answer: B

Explanation:
Yes! To concatenate fields, they must be of same data type. However, there is a workaround which we can use
- Type casting. See below:

Here, State and City are Strings, but Postal Code? Nope. It's an Integer. So we can simply use the STR() function to convert it into a String, and hence the entire equation becomes valid!

NEW QUESTION # 157
Which of the following points are True about Viz Animations?

A. Animations work well with maps, polygons, and density marks in web
browsers
B. It is possible to turn them on for the entire workbook at once
C. They can be turned on for certain worksheets only
D. Sequential animations take more time but make complex changes
clearer by presenting them step-by-step

Answer: B,C,D

Explanation:
All of the given options are true except - Animations work well with maps, polygons, and density marks in web browsers.
From the official documentation:

As seen above, we can either turn the animations for the entire workbook (upper red box), or only for the current sheet ( lower red box )
1) Simultaneous animations
The default simultaneous animations are faster and work well when showing value changes in simpler charts and dashboards.

2) Sequential animations
Sequential animations take more time but make complex changes clearer by presenting them step-by-step.

NEW QUESTION # 158
Which action describes the process for changing a measure so that it automatically aggregates an average instead of a sum?

A. Right-click the field in the Data pane and select Change Data Type to change it.
B. Right-click and drag the field into the view to change it.
C. Add the field to the view, right-click the axis, and select Format to change it.
D. Right-click the field in the Data pane and select Default Properties to change it.

Answer: D

Explanation:
To change a measure so that it automatically aggregates as an average instead of a sum, you should right-click the field in the Data pane and select Default Properties. In the Default Properties menu, you can set the default aggregation for the measure, such as setting it to calculate an average by default when added to a view.

NEW QUESTION # 159
Yes or No: The number of marks will increase when you increase the number of Dimensions in a view

A. No
B. Yes

Answer: B

Explanation:
Of course! As an example, see below:
1) Using the Sample Superstore data, let's plot a bar chart showing the Sales for each Category:

Observe that we have 3 marks - Each bar in a bar chart is called a mark. Similarly, each point in a scatter plot is also a mark , and so on for all charts.
1 row by 3 columns means that clearly on the y-axis (Sales), we have only a single mark - a single continous axis, but 3 different marks (Technology, Furniture and Office supplies ) on the x-axis.
2) Now let's add subcategory to the view as well (another dimension):

Observe that the number of marks has increased - i.e the number of Bars.
Also, notice we now have 1 row and 17 columns. Simply because 1 row = Sales (on the y-axis), and on the x-axis, we have 17 different columns (i.e product sub categories!!)

NEW QUESTION # 160
Using the cwurData table, create a cross-tab showing the number of Publications per Country broken down by Institution, and filtered by Country to only show United Kingdown (UK). For the University of Manchester, what percent of the total publications were contributed in 2014?

NEW QUESTION # 162
What are two correct methods for creating a visual group? Choose two.

A. Select marks in the view.
B. Click the drop-down arrow from the top of the Data pane.
C. Right-click a dimension in the Data pane.
D. Drag a dimension onto another dimension in the Data pane.

Answer: A,C

Explanation:
Two correct methods for creating a visual group are selecting marks in the view and right-clicking a dimension in the Data pane. A visual group is a way of combining related members in a dimension field to create categories or segments in your data. For example, you can create a visual group by selecting several states in a map view and grouping them into regions. You can create a visual group by selecting one or more marks in the view and then clicking the group icon on the tooltip or on the toolbar. This will create a new group field in the Data pane with default names for each group based on their members. You can also create a visual group by right-clicking a dimension in the Data pane and selecting Create > Group. This will open the Create Group dialog box where you can select several members and drag them into groups with custom names8 The other options are not correct methods for creating a visual group. Clicking the drop-down arrow from the top of the Data pane will open a menu with options for creating new fields, folders, sets, bins, etc., but not groups. Dragging a dimension onto another dimension in the Data pane will create a hierarchy, which is a way of organizing data into different levels of detail, not groups9

NEW QUESTION # 163
True or False: It is possible to change the Geographic Role of a dimension

A. False
B. True

Answer: B

Explanation:
A geographic role associates each value in a field with a latitude and longitude value.
Assigning a geographic role based on the type of location (such as state versus postcode) helps ensure that your data is plotted correctly on your map view. For example, you can assign the City geographic role to a field that contains a list of city names.
To assign a geographic role to a field:
In the Data pane, click the data type icon next to the field, select Geographic Role, and then select the geographic role you want to assign to the field.

When you assign a geographic role to a field, Tableau adds two fields to the Measures area of the Data pane: Latitude (generated) and Longitude (generated).
These fields contain latitude and longitude values and are assigned the Latitude and Longitude geographic roles. If you double-click each of these fields, Tableau adds them to the Columns and Rows shelves and creates a map view using the Tableau background map.
